The VQ swap actually isnt that bad.
The RB and VQ swaps both need:
Driveshaft modding, engine and tranny mounts, a little bit of wiring/ learning schematics ( if stock electronics are uses) EFI plumbing, FPR, exhaust, and optional radiator mods.
With the RB youl need a rear sump oil pan and pickup, intercooler, I/C piping, and BOV. With the VQ youl need a different external shifter mount, mod the fuel rails, and trim the x-member. I think they're both equally as "hard", at least from my perspective.
If you do go with the VQ youl end up with a setup that has roughly 50HP more, 100 LBS lighter, and a six speed gear box. Not to mention youl have a powerplant that was sold here in the states so parts/aftermarket are readily availible.
